The Direction of Grassland Use and Ecological Environment Analysis

Abstract

This paper researched the soil and vegetation conditions of BaShang grassland in HeBei province in china by adopting the method of field investigation and data collection .In the topography ,parent material, such as variable section, set the soil profile. Studied of the changes of soil texture and structure of space. Using plant community of minimum area survey method and plant community structure of time and space, ecological gradient survey method, and through the quadrat , collect data. Studied the relationship between plant community structure spacetime and the ecological gradient. Try to find the corresponding land use patterns and understand the BaShang grassland ecological environment change mechanism.
